Title: Manufacture of semiconductor device
Inventor: YAKUSHIJI HISAO
IPC: H01L21/28
Filed: 1984-01-30
Abstract: PURPOSE:To perform a patterning of uniform depth on all areas including small area parts with an excellent controllability when a reactive ion etching (RIE) is conducted by a method wherein the pattern of a positive type resist mask is properly covered by a large-sized negative type resist in proportion to the size of area of the pattern. CONSTITUTION:An oxide film 3, a positive type resist mask patterns 4a and 4b are provided on the semiconductor substrate 1 having a diffusion layer 2, and the pattern 4a having a large area is covered by a negative resist 11. When a reactive ion etching (RIE) is performed, the negative resist 11 is etched at a high speed, but the progress of etching of the resist 11 only is delayed at the pattern 4a part, and the etching of the oxide film 3 is started immediately on the pattern 4b of small area. When the film thickness, the curing temperature and the resist component of the negative resist 11 are changed properly, the depth of the large area pattern 5 and the small area pattern 6 can be adjusted easily so that they will be etched at the identical prescribed value. According to this constitution, each pattern can be uniformly formed in the prescribed depth, thereby enabling to improve the quality of the semiconductor device.

IPC: F23C99/00
Filed: 1991-02-07
Abstract: PURPOSE:To improve performance of evaporation and combustion in a combustion apparatus such as an oil fan heater, etc., with a decrease in NOx generation and an expansion in turn down ratio. CONSTITUTION:A combustion apparatus has such a constitution that a burner head 3 is mounted on an evaporation chamber 1 in which liquid fuel is evaporated, fine burner ports are provided on the upper part of the burner head 3, burner ports larger than the fine burner ports on the lower part (6a<6b<6c), and a wire mesh 7 is attached tight around the circumferential face of the burner head 3. Therefore, flames formed on the burner head 3 are small, resulting in a reduction in NOx generation and the temperature at the upper part of the wire mesh 7 is kept high even when combustion rate is lowered. In addition, the flame stability is good as the burner ports on the lower part of the burner head 3 are larger, and the temperature of the evaporation chamber 1 which is easily affected by the flames can be kept high, so that an excellent evaporation and combustion performance can be achieved.

Title: Production of magnetic core
Inventor: SAWA TAKAO
IPC: H01F27/245
Filed: 1995-01-09
Abstract: PURPOSE:To reduce the iron loss and improve the drop in production yield due to iron core disintegration by laminating or winding up a metallic magnetic thin band at a specified space factor, and then resin-immersing/curing it and cutting off a part of the core. CONSTITUTION:A thin film is laminated or wound up to form a core in a manner that the space factor of thin band made of amorphous magnetic alloy with excellent soft magnetic property 80% or higher. In the case where the space factor is 80% or higher the deterioration of magnetic property of the obtained magnetic core is suppressed significantly since an amount of immersed resin decreases. Next, the obtained core is immersed in a specific resin liquid such as an epoxy. Then, after applying resin-immersing/curing treatment, a part of the core is cut off for used in choke coil, etc. Thus, the iron loss can be reduced and the drop in production yield due to iron core disintegration can be suppressed at the same time.
